Bone marrow is tissue located in the center of your bones, making healthy blood cells that strengthen your immune system and fight off outside infections. A large amount of cells are located in bone marrow, and doctors frequently use hip bone marrow for most transplants, since the stem cells in this area are the most plentiful.
There are a number of different processing methods out there for a cord blood bank to use, and the processing method can ultimately affect the purity of the final product, which we’ll explain in a minute. Once the stem and immune system cells have been isolated and extracted from the plasma and red blood cell, they are mixed with a cryo-protectant and stored in a cryo-bag. We overwrap our bags for added protection and use a technique called “controlled-rate freezing” to prepare the cells for long-term storage. The overwrapped cryo-bag is housed in a protective metal cassette and placed in vapor-phase liquid nitrogen freezer for long-term preservation.
However, parents should know that a child’s own cord blood (stored at birth), would rarely be suitable for a transplant today. It could not be used at present to treat genetic diseases, for example, because the cord blood stem cells carry the same affected genes and. if transplanted, would confer the same condition to the recipient. (See the story of Anthony Dones.) In addition, most transplant physicians would not use a child’s own cord blood to treat leukemia. There are two reasons why the child’s own cord blood is not safe as a transplant source. First, in most cases of childhood leukemia, cells carrying the leukemic mutation are already present at birth and can be demonstrated in the cord blood. Thus, pre-leukemic cells may be given back with the transplant, since there is no effective way to remove them (purge) today. Second, in a child with leukemia, the immune system has already failed to prevent leukemia. Since cord blood from the same child re-establishes the child’s own immune system, doctors fear it would have a poor anti-leukemia effect.
Umbilical cord blood was once discarded as waste material but is now known to be a useful source of blood stem cells. Cord blood has been used to treat children with certain blood diseases since 1989 and research on using it to treat adults is making progress. So what are the current challenges for cord blood research and how may it be used – now and in the future?
Medical staff at the public cord blood bank will check to see if you can donate. If you have had a disease that can be given to another person through blood-forming cells, such as hepatitis B, hepatitis C, or HIV (the AIDS virus), you will likely not be able to donate. However, other medical reasons may still allow you to donate, for example, hepatitis A or diabetes only during your pregnancy (gestational diabetes). The staff at the public cord blood bank will tell you.
A bone marrow or cord blood transplant replaces diseased blood-forming cells with healthy cells. Cells for a transplant can come from the marrow of a donor or from the blood of the umbilical cord collected after a baby is born. Sometimes special qualities of umbilical cord blood make it a better choice of blood-forming cells for transplant.

Parents often complain about cord blood banking costs. This is not an industry where costs can be cut by running a turn-key operation. Each cord blood unit must be individually tested and processed by trained technicians working in a medical laboratory.
After a baby is born, cord blood is left in the umbilical cord and placenta. It is relatively easy to collect, with no risk to the mother or baby. It contains haematopoietic (blood) stem cells: rare cells normally found in the bone marrow.

The immune system has a way to identify foreign cells; it’s what allows the body to defend itself. So although transplants were proving successful after the first in 1956, they were limited to twins because their shared genetic makeup made them 100 percent compatible. This took a turn in 1958, when scientists discovered a protein present on the surface of almost all cells that lets the body know if the cell is one of its own cells or a foreign cell. In 1973, we finally learned enough about these compatibility markers (called human leukocyte antigens or HLAs) to perform the first unrelated bone marrow transplant.
Current research aims to answer these questions in order to establish whether safe and effective treatments for non-blood diseases could be developed in the future using cord blood. An early clinical trial investigating cord blood treatment of childhood type 1 diabetes was unsuccessful. Other very early stage clinical trials are now exploring the use of cord blood transplants to treat children with brain disorders such as cerebral palsy or traumatic brain injury. However, such trials have not yet shown any positive effects and most scientists believe much more laboratory research is needed to understand how cord blood cells behave and whether they may be useful in these kinds of treatments
This is the time of year when many employers and insurance companies hold open enrollment for insurance plans, for the upcoming year. Along with the usual medical, dental, and life insurance plans, many families also opt to enroll in a Medical Flexible Spending Account (or FSA). This type of account offers tax advantages for eligible healthcare costs throughout the year for you and all your dependents. Your Medical FSA is funded by pre-taxed payroll deductions in the amount you choose and covers a wide range of eligible medical expenses including those that result from the diagnosis, care, treatment, or prevention of disease or illness.
After your baby is born, the umbilical cord and placenta are usually thrown away. Because you are choosing to donate, the blood left in the umbilical cord and placenta will be collected and tested. Cord blood that meets standards for transplant will be stored at the public cord blood bank until needed by a patient. (It is not saved for your family.)
Stem cells can be used in treatments for many different types of diseases. One of the main places young stem cells are found is in cord blood, which can be stored at birth and saved for future use if needed. Stem cells are also found in other places in the human body, including blood and bone marrow.
Hematopoietic stem cells can be used to treat more than 70 types of diseases, including diseases of the immune system, genetic disorders, neurologic disorders, and some forms of cancer, including leukemia and lymphoma. For some of these diseases, stem cells are the primary treatment. For others, treatment with stem cells may be used when other treatments have not worked or in experimental research programs.
The American Congress of Obstetricians and Gynecologists and the American Academy of Pediatrics don’t recommend routine cord blood storage. The groups say private banks should only be used when there’s a sibling with a medical condition who could benefit from the stem cells. Families are encouraged to donate stem cells to a public bank to help others.
As the research into umbilical cord blood and it’s therapeutic use for blood diseases has grown, so has the question as to whether people should privately store the cord blood of their offspring for future use. A recent paper on this issue by Mahendra Rao and colleagues advocates the practice of cord blood banking (for treatment of blood diseases) but in the context of public cord blood banks rather than a private cord blood banks. Any adult needing treated would need at least two cord blood samples that are immune compatible. So one sample will not be sufficient. A child might only need one cord blood sample but in the case of childhood leukaemia there is a risk that pre-leukemic cells are present in cord blood sample – and so the child could not use their own cells for therapy.
While banking cord blood is a new experience for many parents, it is a simple one. After all, most mothers are worried about how the delivery will go and don’t want to also be worried about the details of collecting, processing and cryo-preserving their babies’s cord blood. Thankfully, the healthcare provider and the cord blood bank do most of the work. Here are the steps found in cord blood banking:

The proteins stem from three HLA genes, and you inherit one HLA from each parent, or half your HLA markers from your mother and half from your father. This gives siblings a 25 percent chance of being a perfect match, a 50 percent chance of being a partial match and another one-in-four chance of not being a match at all. Unfortunately, about seven out 10 patients who need a transplant don’t have a suitable donor in their family. They can either rely on their own stem cells, isolated before treatment or previously preserved, or try to find a match through a public donor.
Donating cord blood can help families and researchers. If a mother qualifies, the umbilical cord processing and storage is free, and can protect a child from over 80 different diseases. In the next several years, researchers will find new ways to treat even more conditions.
This and all other stem cell therapies since involve introducing new stem cells into the area to encourage the healing process. Often, the stem cell will create a particular type of cell simply because it is in proximity to other cells of that type. Unfortunately, researchers still had a ways to go before they could use stem cells from unrelated persons.
More cord blood donations are desperately needed to cover the transplant needs of adults. Cord blood donations from newborns of diverse ethnic and racial backgrounds are especially needed. Tissue types are inherited, so patients who need a stem cell transplant are more likely to find a matched cord blood unit from someone in their own race or ethnic group.
Cord blood is the blood from the baby that is left in the umbilical cord and placenta after birth. It contains special cells called hematopoietic stem cells that can be used to treat some types of diseases.
The therapuetic potential of cord blood continues to grow. Over the last few years cord blood use has expanded into an area known as regenerative medicine. Regenerative medicine is the science of living cells being used to potentially regenerate or facilitate the repair of cells damaged by disease, genetics, injury or simply aging. Research is underway with the hope that cord blood stem cells may prove beneficial in young patients facing life-changing medical conditions once thought untreatable – such as autism and cerebral palsy.
If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby.
Florida Hospital for Children is conducting an FDA-regulated phase I clinical trial to investigate the use of a child’s stem cells derived from their own cord blood as a treatment for acquired sensorineural hearing loss.
The choices expectant parents make today go beyond finding out the gender of their baby. They span beyond deciding whether to find out if their child, still in the womb, may potentially have a genetic disorder. Today, many parents must decide whether to store their baby’s umbilical cord blood so it will be available to heal their child if at any point in the child’s lifetime he or she becomes sick.

Some controversial studies suggest that cord blood can help treat diseases other than blood diseases, but often these results cannot be reproduced. Researchers are actively investigating if cord blood might be used to treat various other diseases.

The first successful cord blood transplant (CBT) was done in 1988 in a child with Fanconi anemia.[1] Early efforts to use CBT in adults led to mortality rates of about 50%, due somewhat to the procedure being done in very sick people, but perhaps also due to slow development of immune cells from the transplant.[1] By 2013, 30,000 CBT procedures had been performed and banks held about 600,000 units of cord blood.[2]
